A debate that's been raging in churches for centuries could finally be resolved.
The Archbishop of Canterbury, the Pope and other Christian leaders have indicated they'd like to fix the date of Easter, rather than it changing every year according to the moon.
However, there's not likely to be an agreement for the next five to ten years.
Anglican Bishop of Waikato, Helen-Ann Hartley, said the issue's not new.
She said it's been a key part of church life and it has caused a lot of division.
Helen-Ann Hartley saif if some resolution about that were possible, then that's surely a good thing.
It's the most important date in the Christian calendar, but a dispute going back more than 1600 years means the date has never been firmly fixed.
It means Easter can fall anytime between late March, and the end of April.
Archbishop of Canterbury Justin Welby is backing moves to set a fixed date, which were initiated by Egypt's Coptic Pope.
"Pope Tiwardras has put forward the idea to churches in the Eastern tradition, the Western tradition that it be fixed somewhere around the second or third Sunday of April. We've agreed that we support that."
